An Improved Chemical Kinetic Model Reduction in pyMARS for Liquid Propellants

Creator:: Moore, Cailin J.
Abstract:: The aerospace industry uses chemical kinetic models when designing propulsion systems to acquire specific details about the rate of chemical reactions, heat release, and combustion stability. These models, however, are too large and stiff to be useful as they can take weeks to run computations on. The pyMARS python package...

Heat-induced compounds in strawberries

Creator:: Sloan, Jerry L.
Abstract:: Dimethyl sulfide, acetaldehyde, isobutyraldehyde, furan, 2-furaldehyde, 2-acetyl furan, and ethyl furoate were produced when pureed strawberries were heated to 120° C. for 30 minutes. Shorter heating periods were sufficient to produce the first three compounds. With the exception of acetaldehyde, none of the heat-induced compounds were detected in unheated, pureed...

Vegetation composition and response to fire of native Willamette Valley wetland prairies

Creator:: Pendergrass, Kathy L. (Connelly)
Abstract:: Fires set by Native Americans were important in shaping and maintaining Willamette Valley prairie plant communities. With fire exclusion after Euro-American settlement in the 1840's, composition of the remaining prairies shifted toward shrub and tree dominance with a concomitant decline in endemic prairie plant populations. I hypothesize that by restoring...

Assessing Exposures and Simplifying Complex Mixtures of SVOCs for Hazard Characterization using Alternative Model Systems

Creator:: Rivera, Brianna N.
Abstract:: Throughout their lifetime individuals are exposed to complex mixtures of chemicals. The study of chemical mixtures is an internationally recognized research priority, but seemingly complex challenge. To reduce the intricacy of studying mixtures, researchers have identified different prioritization methods based on exposure or the toxicity of chemicals. However, understanding the...

Tracking of Melt Pool Motion Using Numerical Analysis of Laser Powder Bed Fusion

Creator:: Cox, Bryce
Abstract:: Laser Powder Bed Fusion (LPBF) is a process commonly used to create additively manufactured metal parts. The flexibility and complexity allowed by the LPBF process provides opportunity for significant advancement in multiple industries as parts can be customized in shape and function for specific needs. These benefits can be compounded...

A procedure for estimating the carbon budget of terrestrial ecosystems in the former Soviet Union by geographic information system analysis and classification of AVHRR derived Global Vegetation Index

Creator:: Gaston, Greg G.
Abstract:: The purpose of this research was to develop methods for using geographic information system (GIS) analysis and unsupervised classification of Global Vegetation Index (GVI) images to improve carbon budget estimates of the former Soviet Union (FSU). A GIS was used to locate the geographic distribution and estimate the area of...

Multiscale Methods and Energy Stable Discretizations for Maxwell’s Equations in Linearand Nonlinear Materials

Creator:: Sakkaplangkul, Puttha
Abstract:: In this dissertation, we introduce a family of fully discrete finite difference time-domain (FDTD) methods for Maxwell’s equations in linear and nonlinear materials. Onecategory of methods is constructed using multiscale techniques involving operator splittings. We present the sequential splitting scheme, the Strang Marchuk splitting scheme,the weighted sequential splitting scheme including...
